A tamper-resistant lock assembly comprising a plate having a slot for receiving a key, the slot extending through the plate from an opening in a front face thereof to an exit in an opposing rear face thereof, the opening having a first profile and the exit having a second, different profile, the key comprising a shaft having a bit extending therefrom, the bit being formed of a shape memory material and being pre-configured such that its cross-sectional shape in its temporary form matches the first profile and the bit can be inserted through the slot via the opening and, upon application of a predetermined external stimulus, returns to a permanent form in which its cross-sectional shape matches the second profile and the bit can be retracted from the slot via the exit.

Example product security devices and associated methods are provided. An example product security device may include a first jaw and a second jaw that are operably coupled together to slide between an open position and a closed position. The example product security device may include a locking mechanism. In a locked state, the locking mechanism may permit movement of the first jaw towards the second jaw but prevent movement away from the second jaw. The example product security device may also include a product engagement pin. The product engagement pin may fasten the product security device to a product by piercing through the product and being received by the second jaw. A shroud having a shroud orifice may surround the product engagement pin and be operably coupled to the first jaw such that the shroud is movable relative to the product engagement pin. The example security device may also include a signal emitting component, a QR code, a barcode, or combination thereof.

A system for providing access to delivery locations with added security. The system can include a database of images (or other data) of keys associated with a plurality of delivery addresses, or secure delivery locations. When a special handling itemi.e., one that cannot safely be left outside the delivery locationis ordered, the system creates a key to provide access to the secure delivery location. The key can be a one-time use, disposable, shreddable, or otherwise temporary key. The system can also utilize one or more video cameras to record some or all of the delivery process to ensure the delivery driver delivers the item(s), destroys or leaves the key, and leaves the secure delivery location locked, among other things. The manufacturing of a key and/or the choice to use secure delivery can be based on the delivery location, product, delivery value, perishability, or other factors.

A key, comprising: a key head; and a key shank (10), characterized in that the key shank (10) includes a torsion section (20) that is formed, in particular cold formed, along a longitudinal axis (L) at least in sections, wherein the key shank (10) includes a base cross-section (26) in a transition portion to the torsion section (20), wherein a cross-section (30) of the key shank (10) protrudes at least in sections beyond the base cross-section (26) in the torsion section (20) in a direction towards the key tip (70).

The invention relates to a method for securing and/or locking an object. At least one metal key element (1.1) which is at least partly provided with at least one coding along the longitudinal direction of the key element is introduced into a key receiving area (2.2). The first coding is read by means of a reading device (3.2) in the key receiving area (2.2). A method is provided in whichthe key element (1.1) is rotated in the key receiving area (2.2) relative to the key receiving area by a user, thereby generating a relative rotational movement, the relative rotational movement is detected, the detected relative rotational movement is converted into a display signal which varies with the rotation, the display signal is imparted to a display means (2.4) for displaying purposes, an additional coding is adjusted on the display means (2.4) in an interactive manner by means of the user by rotating the key element (1.1), and the securing and/or locking or unlocking process of the object (2.1) is actuated on the basis of the additional coding, wherein for securing purposes, an introduced coding can be used by means of a key element, and an additional coding can be used in an interactive manner with the user. A corresponding device carries out the steps using corresponding means.
